Odor neutralization is a mature technology in lagoon odor
control (Bio Triad, 2009). The neutralization system normally consists
of a neutralizer storage tank, a vapor producer, a spreader, and
a control unit. The odor is eliminated through the following steps:
1) converting the stored neutralizer to vapor by heating; 2) sending
the vapor to the distribution line which is located along the lagoon
exterior wall; 3) spreading vapor from the openings facing out the
lagoons to neutralize the odorants. The vapor cover distance is
significant factor of odor control efficiency because the short one
will result in the skip of odor emission while the long one will allow
the waste of the neutralizer. Therefore, the cover distance should be
around the perimeter of the lagoon tank.
